Directional and Multivariate Statistics

Somesh Kumar is Professor in the Department of Mathematics, Indian Institute of Technology (IIT) Kharagpur, India. He did his M.Sc. in statistics followed by Ph.D. at the IIT Kanpur, respectively, in 1984 and 1990. Before joining the IIT Kharagpur in 1994, he taught at the University of Jammu, India, for five-and-a-half years. He has published more than 130 research papers in refereed international journals and book chapters and supervised 15 Ph.D. scholars. His major research interests are in statistical decision theory and inference, in particular on estimation after selection, quantile estimation, estimation of parameters under constraints, two-stage and sequential estimation, problem of classification, inference on directional distributions, limit theorems for dependent models, estimating measures of reliability and entropy, stochastic ordering and bootstrap tests. His research has found applications in diverse fields like agriculture, medical, mechanical, electronic, environmental and ecological studies.

Barry C. Arnold is distinguished Professor Emeritus in the Department of Statistics, University of California, Riverside, USA. He received his Ph.D. in statistics from Stanford University, USA, in 1965. Author of 14 books and more than 275 research papers in reputed peer-reviewed journals and contributed volumes, he has guided 17 Ph.D. scholars and has been on the editorial boards of several journals. His research interests include estimation theory, probability, stochastic processes, mathematical learning models, biological models, characterizations, income distributions, order statistics, inequality measurement, record values, conditionally specified distributions and Bayesian inference.

Kunio Shimizu is Project Professor in the Center for Training Professors in Statistics at The Institute of Statistical Mathematics, Tokyo, Japan. He is also Professor Emeritus in the Faculty of Science and Technology at Keio University, Yokohama, Japan. He has worked extensively in the field of directional distributions, modeling of distributions, classification problems and multivariate methods.
